      CCM patch committed here and retagged.

      DTest patch committed here

      Trunk patch split to 13 patches starts from this one on.

      The existing tests plus new unit tests added. Also, dtests exercise the backward compatibility and test that way that ccm supports the same behavior as Cassandra as regards to configuration parameters loading.

    Description

      We have a bunch of inconsistent names and config patterns in the codebase, both from the yams and JVM properties. It would be nice to standardise the naming (such as otc_ vs internode_) as well as the provision of values with units - while maintaining perpetual backwards compatibility with the old parameter names, of course.

      For temporal units, I would propose parsing strings with suffixes of:

      code
      u|micros(econds?)?
      ms|millis(econds?)?
      s(econds?)?
      m(inutes?)?
      h(ours?)?
      d(ays?)?
      mo(nths?)?
      code

      For rate units, I would propose parsing any of the standard B/s, KiB/s, MiB/s, GiB/s, TiB/s.
      Perhaps for avoiding ambiguity we could not accept bauds bs, Mbps or powers of 1000 such as KB/s, given these are regularly used for either their old or new definition e.g. KiB/s, or we could support them and simply log the value in bytes/s.
